I know it seems like a dumb question, but I'm a little confused about the issue of gem weapons, do they create their own weapons? So all gems can have weapons if they want? Were the crystal gem weapons created by bismuth or by themselves?
That's not dumb - it's a fair question, especially if you aren't super familiar/obsessive when it comes to SU lore.
The answer is - yes, gems create their own weapons.
Gem weapons are a kind of temporary projection of their own bodies, which are made of light. They can be summoned - sometimes multiple times in a single fight - and disappear naturally when they take damage.
We see this with the main Crystal gems. In the original show, Steven's weapon is a shield.
They're not made by anyone but the gem themselves, and they're intuitive and personalized - though the gems don't really get to choose what weapon they have. They seem to just have one that doesn't change. Once they discover it - that's it! It's donezo.
Do ALL gems have weapons? It's debatable. I personally like the idea that all gems COULD have weapons, but there are many that never bother to learn how to summon theirs. Maybe because they don't care about it? Maybe because they were never trained to, or asked to try. Maybe because they have other skills and powers that are way more flexible that take the place of a gem weapon.
Regardless, there ARE gem weapons that are just... made.
If you're fighting in the gem war and your summoned weapon ends up being, for example, a shield - well, you're kinda shit outta luck on the offensive side of things. During the war, therefore, Bismuth did indeed act as a weapons supplier to the Crystal Gem Resistance.
She made Rose's sword, for example. That sword isn't summoned nor can it disappear - it's just a well-crafted weapon that Rose carried.
So the answer to your other questions is - kinda both!
